Abstract
Magnetic properties of the Chelyabinsk meteorite were studied in a wide temperature range – up to ~ 1300 K. The analysis shows that the meteorite contains ferromagnetic inclusions of both Fe-Ni alloy and pure iron. It has visually been demonstrated that iron inclusions of the Chelyabinsk meteorite experience no β→γ structural phase transformation.

We examine in detail the magnetic properties of the Chelyabinsk meteorite, with paying special attention to their high temperature behavior
Summary
In several works (e.g., [1,2,3,4]) there authors have shown that the Chelyabinsk meteorite contains metallic impurities of the Fe-Ni alloy and iron. 1. Introduction In several works (e.g., [1,2,3,4]) there authors have shown that the Chelyabinsk meteorite contains metallic impurities of the Fe-Ni alloy and iron. When analyzing already existent literature data on the magnetic properties of meteorites with inherent ferromagnetic inclusions, we have found no works where their authors investigated the range of temperatures T > TCFe. At the same time, in our opinion, such investigations can provide for obtaining important information on the feasible structural transformations characteristic of the iron and its alloys, which can exist in meteorites as a whole and in the Chelyabinsk meteorite in particular.
