“…Our previous study shows a strong correlation among the double exchange (DE), the super-exchange and Coulomb interaction in highly Tb-doped LaMnO 3 (ABO 3 ) [12,13], where the focus was put on the physical properties of A-site-doped (non-magnetic atom site) matrixes. When A-site atoms are substituted by smaller non-magnetic atoms, such as Ca and Sr, electric properties can be modified, leading to changes in magnetic behavior.…”

“…Firstly, the structure distortion is very small because the atom size between Tb and La is nearly the same. As a result, the spin structure of B-site Mn ions is approximately unchanged, and the substitution has little influence on electric property of LaMnO 3 [13]. Secondly, the magnetic property can be greatly manipulated although there are only a few magnetic ions at A-site of LaMnO 3 , making it a potential candidate for an outstanding magnetocaloric material.…”

The linear and nonlinear magnetizations of La 0.9 Tb 0.1 MnO 3 at low temperatures were reported in detail. The temperature dependence of magnetization shows peaks at 50, 100 and 150 K, respectively. When LaMnO 3 is Tb-doped, its magnetic structure exhibits a canted antiparallel spin order. This is different from classical antiferromagnetic (AFM) in which the relaxation behavior takes place at about 150 K. At 50 K, Tb-doped LaMnO 3 exhibits canonical spin glass behavior, arising from the competition of exchange and super-exchange between spins. The peak at 100 K shows neither spin glass behavior nor canted AFM behavior. Its peak value increases with frequency increasing, and the transition temperature of the peak shifts to higher temperatures with frequency increasing. The study of aging behavior at 100 K shows a periodical variable metastability, which is ascribed to the competition between ferromagnetic (FM)-, AFM-and sinusoidal-order interactions. This work should shed a light on understanding the complex magnetic structure of the perovskite oxides.

“…It is well known that finite-size scaling is an important factor in studying the phase transition of infinite matter. In this context, we shall use the finite-size scaling law to deduce the critical temperature as the source size tends to infinity [40,[57][58][59]. We apply the extrapolation rule…”

Based on the isospin-dependent quantum molecular dynamics model, finite-size scaling effects on nuclear liquid-gas phase transition probes are investigated by studying the de-excitation processes of six thermal sources of different sizes with the same initial density and similar N/Z. Using several probes including the total multiplicity derivative (dMtot/dT ), second moment parameter (M2), intermediate mass fragment (IMF) multiplicity (NIMF ), Fisher's power-law exponent (τ ), and Ma's nuclear Zipf's law exponent (ξ), the relationship between the phase transition temperature and the source size has been established. It is observed that the phase transition temperatures obtained from the IMF multiplicity, Fisher's exponent, and Ma's nuclear Zipf's law exponent have a strong correlation with the source size. Moreover, by employing the finite-size scaling law, the critical temperature Tc and the critical exponent ν have been obtained for infinite nuclear matter.

“…Perovskite manganites have received considerable attention in recent years because of their (anti)ferromagnetic and ferroelectric properties, as simultaneous ferroic orders in the same phase can provide an additional degree of freedom in multifunctional device design [1][2][3][4][5][6]. The significant magnetoelectric properties can be applied in various ways to sensors, memories, transducers, etc.…”

Orthorhombic HoMnO 3 films with a-axis orientations were prepared epitaxially on Nb-1.0wt%-doped SrTiO 3 single crystal substrates by using the pulsed laser deposition technique to fabricate all-oxide heterojunctions. X-ray diffraction and atomic force microscopy were then used to characterize the films. The temperature dependent current-voltage measurement displayed diode-like rectifying behavior, and the forward current was perfectly fitted using the thermionic emission model. The ideality factor and built-in potential were suggested. heterojunctions, orientation, rectifying behavior
