- Аннотация: The aim of the research is to obtain the geomagnetic field intensity data on the base of the arhaeomagnetic study of ancient ceramics of the Bronze Age in the Eastern Europe. The samples of the fired ceramic were collected by the team of the Institute of Archeology RAS during the work of the Upper Volga Archaeological Expedition. The archaeological settlements Sakhtysh-I (56°78'.95 N, 40°44'.26 E) and Sakhtysh -II (56°78'.27 N, 40°45'.01 E) are situated in Teikovo district of the Ivanovo region of Russia. The studied collection of ancient ceramics consist of 54 pottery samples belongs to four types: the Fatyanoid, the Textile, the Stroked cultures and Bronze Age ceramics. The composition of the ferromagnetic fraction presented in the studied archaeological samples was studied by the thermomagnetic analysis (TMA). TMA showed that the Curie temperature for all samples is near 570-575 °C. Hysteresis measurements indicate that the size of magnetic grains lies in a pseudo single domain area. The determination of the paleointensity was carried out by modified Thellier method using a three-component magnetometer (Orion, Russia). Based on the date of the Textile and the Stroked cultures, their ceramic samples are corresponded to the ~ 1700-1000 years BCE range, while the Fatyanoid culture corresponds to the ~ 2000-1700 years BCE. The obtained determinations provide new data on geomagnetic field intensity variations during the Bronze Age. Using our previous research [Nachasova I. E., Pilipenko O. V., et al., 2018.] we can construct a curve of geomagnetic field intensity variations during V-II millennia BCE. The geomagnetic field intensity varied mainly in the range from ~44 μT to ~60 μT during the II millennium BCE. The obtained data indicate that the increase of the paleointensity mean value took place in the II millennium BCE as compared to the second half of IV millennium - III millennium BCE.
