Experimental studies of the magnetic and structural properties solid solutions Mn1-xCoxNiGe system in a wide range Co concentrations (0.05≤ x≤ 0.8), temperatures (5 K≤ x≤600 K) fields (0.016 T≤ 13.5 T) have revealed number nontrivial magnetocaloric features this system. The latter include: 1) change nature phase transitions from magnetostructural 1st order paramagnetism-antiferromagnetism 0.15)...
We discuss different magnetic phenomena observed in carbon-based structures, in particular the diamagnetism, paramagnetism and ferromagnetism observed in graphite, disordered carbon, fullerenes and irradiated carbon structures.
Herein, we show a new photomagnetic system that gives rise to the magnetic transformation from diamagnetism to paramagnetism by photoinduced intramolecular charge transfer in the polyoxometalate-based organic-inorganic hybrid, [(VMo6O22)2{O2C(CH2)2CO2}3] (1).
