Change from first- to second-order magnetic phase transition in La 2 / 3 ( C a , S r ) 1 / 3 MnO 3 perovskites
TL;DR: In this article, it was shown that not all the title perovskites exhibit a first-order transition at their Curie temperatures, while all the second-order ones do.
Journal ArticleDOI
High-temperature spin dynamics in CMR manganites: ESR and magnetization
M.T. Causa,M. Tovar,Alberto Caneiro,Fernando Daniel Prado,G. Ibanez,C.A. Ramos,Alejandro Butera,B. Alascio,Xavier Obradors,S. Piñol,Francisco Rivadulla,Carlos Vázquez-Vázquez,M. A. López-Quintela,José Rivas,Yasuhiro Tokura,S. B. Oseroff +15 more
TL;DR: In this paper, the electron spin resonance (ESR) and dc susceptibility measurements in Mn perovskites up to 1000 K were performed and a single relaxation mechanism related to spin-only interactions was proposed.
Journal ArticleDOI
Tuning of the magnetocaloric effect in La0.67Ca0.33MnO3−δ nanoparticles synthesized by sol–gel techniques
TL;DR: In this article, the effect of progressive reduction of the annealing temperature on the magnetocaloric effect (MCE) of La2/3Ca1/3MnO3−δ nanoparticles synthesized by the sol-gel technique is reported.
Journal ArticleDOI
Intergranular magnetoresistance in nanomanganites
TL;DR: In this article, the magnetic and transport properties of mixed-valence manganite nanoparticles were analyzed using a sol-gel method, which allowed the authors to control particle size and obtain new properties of the archetypal ferromagnetic- metallic compound La2/3Ca1/3MnO3.
Journal ArticleDOI
Reduction of the bulk modulus at high pressure in CrN.
Francisco Rivadulla,Manuel Bañobre-López,Camilo X. Quintela,A. Piñeiro,Victor Pardo,Daniel Baldomir,M. A. López-Quintela,José Rivas,C.A. Ramos,Horacio Salva,Jianshi Zhou,John B. Goodenough +11 more
TL;DR: A pressure-induced cubic-to-orthorhombic transition at approximately 1 GPa in CrN is reported, showing an unexpected reduction of the bulk modulus, K0, of about 25% in the high-pressure (lower volume) phase.
