Determining magnetic nanoparticle size distributions from thermomagnetic measurements [PDF]

Applied Physics Letters, 2010
Thermomagnetic measurements are used to obtain the size distribution and anisotropy of magnetic nanoparticles. An analytical transformation method is described which utilizes temperature-dependent zero-field cooling magnetization data to provide a quantitative measurement of the average diameter and relative abundance of superparamagnetic nanoparticles.

Exotic hysteresis of ferrimagnetic transition in Laves compound TbCo2

Materials Research Letters, 2020
We observed exotic hysteresis behavior in the ferrimagnetic transition of a Laves compound TbCo2. While positive thermal hysteresis was observed in zero-field calorimetric measurements, inverse thermal hysteresis was observed in thermomagnetic ...

The analysis of thermomagnetic measurements in weak fields

Journal de Physique et le Radium, 1959
The thermal changes which accompany magnetization in weak fields were measured for a series of nickel-cobalt alloys of different coercivities to provide information concerning the magnetic processes which produce an interesting phenomenon, known as the " dip " between — Hc and + Hc.
