Magnetic forces in and on a magnet

Discrete & Continuous Dynamical Systems - S, 2019
Given the shape of a magnet and its magnetization, point by point, which force does it exert on itself, also point by point? We explain what 'force' means in such a context and how to define it by using the Virtual Power Principle. Mathematically speaking, this force is a vector-valued distribution, with Dirac-like concentrations on surfaces across ...

Spin‐Selective Anisotropic Magnetoresistance Driven by Chirality in DNA

Advanced Functional Materials, EarlyView.
It is shown that magnetoresistance (MR) measurements carried out as a function of angular dependence between the magnetic field and a chiral (DNA) interface provide a valuable new insight into the charge transport mechanism associated with the chiral‐induced spin selectivity (CISS) effect.

Switching dynamics between metastable ordered magnetic state and nonmagnetic ground state - A possible mechanism for photoinduced ferromagnetism -

, 1998
By studying the dynamics of the metastable magnetization of a statistical mechanical model we propose a switching mechanism of photoinduced magnetization.

Equivalent Electrical Model of an Inductor Excited by a Triangular Current Including Saturation

Communications, 2020
A model for an equivalent electrical circuit designed for a ferrite (3C90) inductor usually used in power converters excited by a non-sinusoidal current appropriate for use in power electronics is proposed. This study, based on 3D finite element analysis,

Enhanced Magnetization Switching Efficiency via Orbital‐Current‐Induced Torque in Ti/Ta (Pt)/CoFeB/MgO Structures

Advanced Functional Materials, EarlyView.
The orbital‐current‐induced torque is investigated as an efficient method for controlling magnetization direction. By introducing Ti as an orbital current source in Ti/Ta (or Pt)/CoFeB/MgO structures, the switching current is reduced by ∼25% compared to a conventional spin‐orbit torque structure of Ta/CoFeB/MgO.

Extremely broad hysteresis in the magnetization process of α-Dy2S3 single crystal induced by high field cooling [PDF]

, 2012
α-Dy2S3 possesses orthorhombic crystal structure having two crystallograpically inequivalent Dy sites. Magnetization process of α-Dy2S3 single crystal after cooling in the high magnetic field of 18 T has been investigated.

High‐Entropy Magnetism of Murunskite

Advanced Functional Materials, EarlyView.
The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

Hysteresis in mesoscopic superconducting disks: the Bean-Livingston barrier

, 1998
The magnetization behavior of mesoscopic superconducting disks can show hysteretic behavior which we explain by using the Ginzburg-Landau (GL) theory and properly taking into account the de-magnetization effects due to geometrical form factors.

Magnetization dynamics in the single-molecule magnet Fe8 under pulsed microwave irradiation [PDF]

, 2007
We present measurements on the single molecule magnet Fe8 in the presence of pulsed microwave radiation at 118 GHz. The spin dynamics is studied via time resolved magnetization experiments using a Hall probe magnetometer.
