Itinerant-electron Antiferromagnetic - Ferromagnetic Transition in La(Fe0.875Al0.125)13 Intermetallic Compound

Ferromagnetic-antiferromagnetic transition in „La-R...4Ba2Cu2O10

Cuprate La-R 4Ba2Cu2O10 shows ferromagnetic to antiferromagnetic phase transition by replacing La ions with rare earth R=Nd, Sm, Eu, and Gd ions at low temperature. We propose that the transition is caused by a competition between antiferromagnetic superexchange interaction of Cu spins via La ions and ferromagnetic superexchange interaction due to Hund’s rule coupling of spins of holes on oxyge...

Griffiths phase behaviour in a frustrated antiferromagnetic intermetallic compound

The rare coexistence of a Griffiths phase (GP) and a geometrically frustrated antiferromagnetism in the non-stoichiometric intermetallic compound GdFe0.17Sn2 (the paramagnetic Weiss temperature θp ~ -59 K) is reported in this work. The compound forms in the Cmcm space group with large structural anisotropy (b/c ~ 4). Interestingly, all the atoms in the unit cell possess the same point group sym...

Antiferromagnetic transition in EuFe2As2: a possible parent compound for superconductors

Ternary iron arsenide EuFe2 As2 with ThCr2 Si2 -type structure has been studied by magnetic susceptibility, resistivity, thermopower, Hall, and specific-heat measurements. The compound undergoes two magnetic phase transitions at about 200 and 20 K, respectively. The former was found to be accompanied with a slight drop in magnetic susceptibility (after subtracting the Curie-Weiss paramagnetic c...
