Eye, magnetism and magnets

British Journal of Ophthalmology, 2014
Mankind has always been familiar with the magnetism or drawing power of the eyes. Eye contact between mother and child is a strong force in bonding between the two. Eye contact is also the initial signal of attraction between two individuals, triggering special emotions especially if the attraction is mutual.

Ultrafast phononic switching of magnetization

Nature Physics, 2020
Identifying efficient pathways to control and modify the order parameter of a macroscopic phase in materials is an important ongoing challenge. One way to do this is via the excitation of a high-frequency mode that couples to the order, and this is the ...

Magnetization of High-Field Superconductors

, 1964
Experimental results and phenomenological theory based on the sponge model for hysteretic high-field superconductors are given. After developing the exposition for static magnetization, the response of the superconductors to alternating fields ...

A Stable Pentagonal Bipyramidal Dy(III) Single-Ion Magnet with a Record Magnetization Reversal Barrier over 1000 K.

Journal of the American Chemical Society, 2016
Single-molecule magnets (SMMs) with a large spin reversal barrier have been recognized to exhibit slow magnetic relaxation that can lead to a magnetic hysteresis loop. Synthesis of highly stable SMMs with both large energy barriers and significantly slow

Quantum tunneling of magnetization and related phenomena in molecular materials.

Angewandte Chemie, 2003
Molecules comprising a large number of coupled paramagnetic centers are attracting much interest because they may show properties which are intermediate between those of simple paramagnets and classical bulk magnets and provide unambiguous evidence of ...

Magnetization switching by spin-orbit torque in an antiferromagnet-ferromagnet bilayer system.

Nature Materials, 2015
Spin-orbit torque (SOT)-induced magnetization switching shows promise for realizing ultrafast and reliable spintronics devices. Bipolar switching of the perpendicular magnetization by the SOT is achieved under an in-plane magnetic field collinear with an

Tweezing of Magnetic and Non‐Magnetic Objects with Magnetic Fields

Advanced Materials, 2017
Although strong magnetic fields cannot be conveniently “focused” like light, modern microfabrication techniques enable preparation of microstructures with which the field gradients – and resulting magnetic forces – can be localized to very small dimensions.

Magnetism and Magnetic Fields

2012
The study of magnetism and magnetic fields readily follows the study of electricity and is normally a second-semester topic in a first-year physics course. One of the difficulties that a teacher may encounter is that students often confuse magnetic poles with electric charges.

Covalent magnetism and magnetic impurities

Journal of Physics: Condensed Matter, 2013
We use the model of covalent magnetism and its application to magnetic insulators applied to the case of insulating carbon doped BaTiO3. Since the usual Stoner mechanism is not applicable we study the possibility of the formation of magnetic order based on a mechanism favoring singly occupied orbitals.
