Journal ArticleDOI

Specific heat anomalies in La 1 − x Sr x Mn O 3 ( 0.12 ⩽ x ⩽ 0.2 )

TL;DR: In this article, Liu et al. showed that the phase transition observed below the Curie temperature for all the compositions studied and no evolution of its order from the second to the first in the range $0.17$ to 0.14$ occurs.
Journal ArticleDOI

Electric-field and current-induced metastability and resistivity relaxation in La 0.8 Ca 0.2 Mn O 3 at low temperatures

TL;DR: In this paper, phase separation and coexistence of metallic and insulating ferromagnetic phases with different orbital order at a wide temperature range are claimed to be responsible for the observed electric-field and current effects.
Journal ArticleDOI

Thermal properties of monoclinic KLu(WO4)2 as a promising solid state laser host.

TL;DR: Simulation of the temperature distribution in a bulk sample of KLu(WO4)2 with dimensions 3x3 x 3 x 3 mm(3) shows that pump and laser beam directions along the N(p) principal optical axis in terms of thermal effects are preferable because the propagation is along a quasi-isothermal path.
Journal ArticleDOI

Magnetic field-induced transitions in geometrically frustrated Co 3 V 2 O 8 single crystal

TL;DR: In this paper, the magnetic field induced phase transitions observed for various orientations of magnetic field were investigated as a function of temperature and magnetic field and it was suggested that the jump, observed for $H\ensuremath{-parallel}\mathbit{c}$-axis have been observed below $6\phantom{\rule{0.3em}{0ex}}\mathrm{K}$.
Journal ArticleDOI

Magnetic, thermodynamic, electronic, and transport properties of Ce Ni 4 Al

TL;DR: In this paper, the TB LMTO method was used to estimate the hybridization between the f$-level and conduction states and revealed a small value of approximately 37\phantom{\rule{0.3em}{0ex}}
