Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The isobaric heat capacity of LaSrMnFeO5.5 ferrite is investigated within the temperature range of 298.15–673 K by a calorimetric method. On the curve of the dependence of the heat capacity on temperature, the λ-type effect is revealed relating to a phase transition of the second kind. Temperature dependencies of the thermodynamic functions S 0(T), H 0(T) -H 0(298.15), and Φ xx (T) are calculated. The temperature dependencies of permittivity and electrical resistance are studied within the temperature range of 303–493 K, and the results show that the composition under study has semiconductor properties.
