This in vitro study examines a spinning oscillating magnetic field (sOMF) generated by an Oncomagnetic device and reports selective toxicity in glioma cancer cells. The abstract attributes effects to ROS-dependent inhibition of mitochondrial complex I, with downstream oxidative stress, DNA damage, cell-cycle arrest,…

This mini-review discusses the radical pair mechanism as a plausible biophysical route by which external magnetic fields could influence biochemical processes in living systems. It is intended as a primer for magneto-oncology researchers to assess whether observed magnetic-field-related biomedical effects may be…

This in vitro/ex vivo study tested whether different magnetic-field configurations alter ketoprofen properties and its transdermal delivery in porcine skin using Franz diffusion cells. The authors report no change in ketoprofen molecular structure, but subtle changes in crystal structure and physicochemical…

This materials study examines how a high magnetic field affects crystallization during isothermal annealing of [(FeCo)BSi]Nb4 bulk metallic glass. The authors report that the field promotes α-(Fe,Co) precipitation and suppresses boride formation, yielding a nanocomposite microstructure with α-(Fe,Co) dispersed in an…

This engineering study evaluates mechanical hoop strain in a YBCO coated-conductor double-pancake coil intended for a high-field HTS insert in an NMR magnet. The authors present experimental strain-gauge measurements and analytical stress/strain calculations for a coil operated with and without a stainless steel…

This engineering study describes a method to improve the sensitivity of Faraday-effect-based heterodyning fiber laser sensors for magnetic field measurement. It reports an inverse relationship between magnetic-field sensitivity and intra-cavity linear birefringence, supported by theory and experimental birefringence…

This engineering study reports fabrication of a biodegradable PLLA shape-memory nanocomposite incorporating surface-modified Fe3O4 nanoparticles. The composite showed improved tensile/mechanical and shape-memory properties compared with PLLA, and shape recovery could be triggered by an alternating magnetic field.…

This study examines how spatial inhomogeneity affects a two-dimensional noncentrosymmetric superconductor in an in-plane magnetic field, motivated by LaAlO3-SrTiO3 interfaces. The authors report that spatial variation of Rashba spin-orbit coupling can generate local magnetic flux patterns through a field-induced…

This paper proposes that Pb nanowires created by repeated indentation of a Pb tip on a Pb substrate may exhibit topological superconducting properties in an external magnetic field. The authors analyzed conductance curves from different nanowires and report that, in a few cases, the critical current shows a peculiar…

This theoretical study analyzes quench dynamics in the Kondo model on the Toulouse line in the presence of a local magnetic field. The authors report exact analytical results for local spin dynamics, finding that relaxation timescales are set by the Kondo scale. They also describe damped transient oscillations in…

This study reports slow relaxation of magnetoresistance in selectively doped p-GaAs-AlGaAs structures following application of a magnetic field. The authors emphasize efforts to rule out temperature fluctuation artifacts and state that the main relaxation features remain. They interpret the phenomenon using a…

This theoretical/physics study investigates spectral properties of a spin-1/2 Heisenberg antiferromagnet on an anisotropic triangular lattice in a magnetic field. It reports that interchain interactions in a magnetic field generate dominant modes that behave as quasiparticles, featuring anomalous incommensurate…

This paper presents numerical methods to compute ground-state solutions of spin-1 Bose-Einstein condensates in a uniform magnetic field. The approach uses normalized gradient flow with an additional normalization condition and enforces conservation of total mass and magnetization. The authors compare numerical…

This paper studies chaotic mixing driven by breakup and reformation of a magnetic particle chain under a rotating magnetic field using direct numerical simulation. The authors report that chain motion and the degree of chaos depend strongly on the Mason number, and that a limited Mason number range produces repeated…

This Physical Review Letters paper reports a method to reverse electric polarization in multiferroic TbMnO3 using a rotating magnetic-field direction, without applying an electric field or heat. The authors state that the direction of magnetic-field-induced polarization along the a axis is retained as a memory even…

This physics study reports ultranarrow optical absorption and two-phonon excitation spectroscopy of Cu2O paraexcitons in a high magnetic field at 1.2 K. A magnetic field enabled observation of an otherwise forbidden paraexciton absorption line and allowed measurement of field-dependent oscillator strength and energy…

This Physical Review Letters study investigates phase competition between spin- and orbital-ordered states in a DyVO3 single crystal. The abstract reports reentrant temperature-driven transitions in spin ordering and orbital ordering. It also reports that an applied magnetic field can switch between orbital-ordered…
