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.

Magnetic phase diagrams of Gd-H, Tb-H, Dy-H systems
EPJ Web of Conferences, 2018 We study the impact of hydrogen impurity on the magnetic phase transition temperatures of the high purity rare-earth metals Gd, Tb and Dy. Prior to hydrogenation, the rare earths were purified by the vacuum distillation method.

Thermomagnetic analysis of natural and synthetic hematite
Geophysical Research Letters, 1977 Thermomagnetic analysis of natural and synthetic samples containing hematite have confirmed Schwarz's (1969) observations that 1.) extensive reduction of hematite to magnetite occurs when the experiment is performed in vacuum but not when it is performed in air 2.) the reduction is arrested when the sample is heated in air before the vacuum run.

475 °C Embrittlement in a duplex stainless steel UNS S31803
Materials Research, 2001 The susceptibility of a duplex stainless steel UNS S31803 to thermal embrittlement at 475 °C was evaluated by means of mechanical tests (impact energy and hardness), magnetic measurements (hysteresis and thermomagnetic analysis) and scanning electron ...

The thermomagnetic analysis of meteoric and artificial nickel-iron alloys [PDF]
Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1907 Abstract The object of the paper is to show how a study of the variation with temperature of the magnetic properties can be applied (1) to the solution of the problem of the composition and structure of meteoric iron, and (2) to throw light upon the changes that take place with change of temperature in the internal structure of nickel-

Thermomagnetic Analysis: Experimental Factors
Journal of geomagnetism and geoelectricity, 1969 Thermomagnetic analysis along with conventional reflection microscopy and magnetic powder analysis can be used to evaluate the alteration state of the magnetic fraction in a rock. The alteration state is positive or negative depending on the sense of change in a magnetic parameter (±ΔM) observed during thermomagnetic analysis.

Thermodynamic and Mechanical Analysis of a Thermomagnetic Rotary Engine
Journal of Physics: Conference Series, 2016 A heat engine in magnetic system had three thermodynamic coordinates: magnetic intensity , total magnetization , and temperature T, where the first two of them are respectively analogous to that of gaseous system: pressure P and volume V. Consequently, Carnot cycle that constitutes the principle of a heat engine in gaseous system is also valid on that ...
