Quantum phase transitions in disordered magnets
… the effects of quenched weak disorder on quantum phase transitions in disordered magnets. The presence of disorder in the system can lead to a variety of exotic phenomena, e.g., the smearing of transitions or quantum Griffiths singularities. Phase transitions are smeared if individual spatial …

Magnetic, thermodynamic and transport properties of the magnetic semiconductor Fe₁₋xCoxS₂ and superconducting LaSb₂
… the observed features of spin clusters and the Griffiths phase. This inhomogeneous magnetic state can be used to explain the resulting physical properties, including the NFL behavior as evidenced by the increase of C/T at very low temperature in proximity to the zero-T critical point. A second …

Critical behavior and transport properties of lanthanum manganite
… slope. This is indicative of the presence of a Griffiths phase where ferromagnetic clusters emerge in a paramagnetic background well before the entire system orders. The manganites' magnetic heat capacity peak has been observed to shift upward in temperature with applied magnetic field unlike …

Estudo da dupla Perovskita La2MnFeO6 preparada por reação de estado sólido
… measurements, the LFMO’s have a ferrimagnetic phase transition at approximately 10 K, as data fit using the medium field theory. Peaks in the specific heat of the samples at higher temperatures were observed, occurring at different temperatures, depending on the degree of ordering of each LFMO …
