The effect of pressure on magnetic properties of LaCoO3 is studied experimentally and theoretically. The pressure dependence of magnetic susceptibility χ of LaCoO3 is obtained by precise measurements of χ as a function of the hydrostatic pressure P up to 2 kbar in the temperature range from 78 K to 300 K. A pronounced magnitude of the pressure effect is found to be negative in sign and strongly temperature dependent. The obtained experimental data are analysed by using a two-level model and DFT…

Effects of Temperature and Pressure on the Magnetic Properties of La1–xPrxCoO3
For La1–xPrxCoO3 cobaltites (x = 0, 0.1, 0.2, and 0.3), the dependence of magnetic susceptibility χ(T) is studied in the temperature range 5–400 K. Also, the crystal structure of these cobaltites is

Pressure Dependence of the 100 K Spin-State Transition in LaCoO3.
The pressure dependence of the 100 K spin-state transition in LaCoO 3 is investigated through magnetization measurement under pressures of up to 18.2 kbar. The energy gap, Δ, between the low-spin
Understanding the thermoelectric properties of LaCoO3 compound
Abstract We present the thermoelectric (TE) properties of LaCoO compound in the temperature range 300–600 K. The experimental value of Seebeck coefficient () at 300 K is found to be V/K. The value of
Electronic structure, magnetic properties, and mechanism of the insulator–metal transition in LaCoO3 taking into account strong electron correlations
The electronic structure of LaCoO3 at finite temperatures is calculated using the LDA+GTB method taking into account strong electron correlations and possible spin crossover upon an increase in
Ultrasonic Measurement of LaCoO3 —Evidence for the Orbital-Order Fluctuation—
The sound velocity propagating along [111] of LaCoO 3 has been measured from 4 to 580 K for longitudinal ( L ) and transverse ( T ) sounds with frequencies, f , of 10 to 100 MHz. A comparison of the
Mechanism of spin crossover in LaCoO3 resolved by shape magnetostriction in pulsed magnetic fields
Measurements of both longitudinal and transversal magnetostriction allow us to separate magnetovolume and magnetodistortive changes, and provide compelling evidence that above Hc LaCoO3 adopts a correlated low spin/high spin state.

Intermediate-spin state and properties of LaCoO3.
The electronic structure of the perovskite LaCoO3 for different spin states of Co ions was calculated in the local-density approximation LDA+U approach and shows that Co 3d states of t(2g) symmetry form narrow bands which could easily localize, while e(g) orbitals, due to their strong hybridization with the oxygen 2p states, form a broad sigma* band.

Spin-state transition in LaCoO3: direct neutron spectroscopic evidence of excited magnetic states.
This work interprets an excitation in LaCoO3 as originating from a transition between thermally excited states located about 120 K above the ground state, and discusses the nature of the magnetic excited state in terms of intermediate-spin versus high-spin states.
