    (SPIE, 2025) Aplesnin, Sergey; Kharkov, Anton; Sitnikov, Maksim; Bandurina, Olga; Uvaev, Ilya; Voronova, Evgenia; Abdelbaki, Hichem
    hermoelectric effects in the solid solution Mn1-xLuxS (x ≤ 0.2) in a wide temperature range without a field and in a magnetic field of 12 kOe are studied. The temperatures at wich a change in the sign of the thermoelectric power and the maxima of the Seebeck coefficient below Neel temperature in a magnetic field are found. The thermal expansion coefficients are measured to establish a correlation with the thermoelectric power. The thermoelectric power anomalies are explained within the framework of the orbital glass model and a change in the type of magnetic order in a magnetic field in a magnetically ordered region
