***General Introduction*** 
This dataset contains data collected during the PhD of Lei Han in Tsinghua University, which provides the source data of all the figures in the publication of "Observation of Non-volatile Anomalous Nernst Effect in Mn5Si3 with Collinear Neel Vector". 

***Purpose of the experiments*** 
This work realize non-volatile anomalous Nernst effect in an altermagnet Mn5Si3 thin film with strain, where the Berry curvature from the intersections of spin-splitting bands instead of tiny net moment determines anomalous Nernst conductivity. 

***Description of the data in this data set*** 
The data for different figures in the publication of "Observation of Non-volatile Anomalous Nernst Effect in Mn5Si3 with Collinear Neel Vector" are presented in different sheets of the excel file. In each sheet, the first row includes the x and y axis of corresponding figure, with variable and units provided. 

***Test equipment*** 
The X-ray magnetic linear dichroism and low-temperature XRD experiments were carried out at the Shanghai Synchrotron Radiation Facility (SSRF) in China. Longitudinal and transverse voltage were collected by Keithley 2182A in a PPMS chamber. Magnetization data were obtained by SQUID. Please note that for the magnetization data, the diamagnetic contribution of substrate was subtracted. For the anomalous Nernst effects measurements, the temperature gradient was calibrated by a thermal equivalent method.
