Critical behaviour of the specific heat of La0.9Ag0.1MnO3 manganite

For the first time the specific heat of polycrystalline La0.9Ag0.1MnO3 manganite near the Curie temperature was precisely measured by AC calorimetry and its critical behaviour was studied. The critical behaviour of the specific heat was approximated by the relationship taking into account corrections to the scaling. The regularities of variations in the universal critical parameters near the critical point are determined, and their values are calculated. Detailed analysis and comparison of the received results with the theoretical predictions and other experimental results was carried out.
