This high field slope is known as high-field paramagnetic susceptibility. The saturation magnetization, MS, of a sample can be calculated from a hysteresis loop by extrapolating the linear high-field part of the loop back to B = 0. MS is a function of all magnetic minerals (ferri- and ...

Monomeric 1 exhibits paramagnetic behavior, whereas polymeric 2 shows the unusual coexistence of superparamagnetic and two-step field-induced metamagnetic behaviors. The antiferromagnetic ground state of 2 does not prevent the dynamic relaxation of the magnetization with the finite-sized effect in the ...

2. Superconducting hysteresis motor is almost identical with conventional hysteresis motor but its rotor is made up of HTS materials (YBCO). The rotor core is constructed with paramagnetic materials. In this HTS hysteresis motor aluminum is used as a paramagnetic material only for mechanical support...
The negative enough zeta potentials are favorable for these iron oxides to electrostatically absorb Fe3+ cations to form a paramagnetic shell. Under an applied magnetic field, this shell will be firstly magnetized and its negative coupling with the post-magnetized iron-oxide core will result in ...

A technique is proposed for demagnetizing correction of the measured magnetization curve and hysteresis loop, i.e., the M∗(Ha) curve, of a ferromagnetic cylinder into the true M(H) curve of the material, where Ha is the uniform applied field provided by a long solenoid and M∗ is th...
For example, in the course of the thermally driven magnetostructural transition, the Gd5Ge2Si2 alloy is converted from the orthorhombic ferromagnetic structure to the monoclinic paramagnetic structure [9], [10]. However, within relatively narrow temperature ranges, the thermally driven magnetostructural...
