As a result, the Curie temperature is markedly increased for the samples with smaller σ2, even if they exhibit a complex ferromagnetic/antiferromagnetic phase-separated state at low temperature.SDOSJournal of Magnetism and Magnetic Materials
Because the magnetic structure of BFO can be approximated to a G-type antiferromagnetism, we considered an antiferromagnetic spin configuration formed by the d electrons. Before geometry optimizations of BFO, we put a amsaygmnemtiectrmyolomweenrtinogf :+th5e μsBp(aμcBe denotes the Bohr ...
which enables the electrical drive of magnetic domains15,16. This effect has been used to achieve the electrical control of the exchange bias of a ferromagnetic layer deposited on top of the antiferromagnetic multiferroic by
Phase separation between novel Bi-stripe order and CE-type charge order in half-doped bilayer manganite LaSr2Mn2O7 We have revealed that a bi-stripe order with the [1 0 0] propagation vector (vertical direction) exists in the A-type antiferromagnetic spin ordered phase ... M Kubota,H Yos...
The electrical and magnetic properties of κ-(BETS)2FeBr4 salt [where BETS = bis(ethylenedithio)tetraselenafulvalene] showed that this system is the first antiferromagnetic organic metal at ambient pressure (TN = 2.5 K). The characteristic field dependence of the magnetization at 2.0 K indicates...
The pattern of moment alignment in the antiferromagnetic state of α-Mn is deduced. Dependent on interatomic distance, both parallel and antiparallel spin couplings are present. Also, for one kind of atom no moment alignment occurs. The magnitudes of the individual moments appear to exceed ...
This result, in combination with the absence of imaginary modes in the phonon density of states, supports the classification of the bixbyite-type phase as a metastable V(2)O(3) polymorph. At ~50 K a paramagnetic to canted antiferromagnetic transition is detected. 展开 ...

utmost interest as the seat of robust magnetism, enabling stable and large magnetization and polarization at application-relevant temperatures, and hence a possible path to the above goal. Also, such a material would quite likely be a ferromagnet, whereas most insulating magnets are antiferromagnetic....
