Spin-state polaron in lightly hole-doped LaCoO_3 (2008)
Podlesnyak, A., Russina, M., Furrer, A., Alfonsov, A., Vavilova, E., Kataev, V., ...
Inelastic neutron scattering (INS), electron spin (ESR) and nuclear magnetic resonance (NMR) measurements were employed to establish the origin of the strong magnetic signal in lightly hole-doped...
Magnetic excitations in the spin-trimer compounds Ca3Cu3-xNix(PO4)4 (x=0,1,2) (2007)
Podlesnyak, A., Pomjakushin, V., Pomjakushina, E., Conder, K., Furrer, A.
Inelastic neutron scattering experiments were performed for the spin-trimer compounds Ca3Cu3-xNix(PO4)4 (x=0,1,2) in order to study the dynamic magnetic properties. The observed excitations can be...
Charge ordering as an alternative to Jahn-Teller distortion (2007)

Effect of light Sr doping on the spin-state transition in LaCoO_3 (2006)
Podlesnyak, A., Conder, K., Pomjakushina, E., Mirmelstein, A., Allenspach, P., Khomskii, D. I.
We present an inelastic neutron scattering study of the low energy crystal-field excitations in the lightly doped cobalt perovskite La_0.998Sr_0.002CoO_3. In contrast to the parent compound LaCoO_3...
Podlesnyak, A., Streule, S., Mesot, J., Medarde, M., Pomjakushina, E., Conder, K., ...
A gradual spin-state transition occurs in LaCoO3 around T~80-120 K, whose detailed nature remains controversial. We studied this transition by means of inelastic neutron scattering (INS), and found...
Spin structure and magnetic phase transitions in TbBaCo2O5.5 (2004)
Plakhty, V. P., Chernenkov, Yu. P., Barilo, S. N., Podlesnyak, A., Pomjakushina, E., Khalyavin, D. D., ...
Spin ordering in TbBaCo2O5.5 and its temperature transformation is studied. Polymorphism due to the oxygen ordering with the average content close to 5.5 is investigated. One of ceramic samples (I),...
Bobrovskii, V., Mirmelstein, A., Podlesnyak, A., Zhdakhin, I.
Exact expressions for the parameters of Stevens Hamiltonian are derived within the framework of a specific model that assumes uniform character of charge density distribution in a certain direction...
