Abstract

Mn oxide materials have long been known to have a large magnetoresistance properties. LA2-2xSr1+2xMn2O7 (or called LSMO 327) has the largest magnetoresistance properties compared to other groups (such as LSMO 113). The preparation of single crystals required a practical method to determine the direction of the axis of single crystals. In this paper, we reported a method of determining the direction of the axis of single crystals by using back-reflection Laue photographs to determine the direction of the axis a, b and c to the direction of crystal growth. We used two samples of single crystal LSMO 327 x = 0.4. By the back-reflection Laue method, we know that c-axis of LSMO 327 single crystals have an angle of 80° to the direction of crystal growth. While the direction of the a-axis and b-axis does not look the same in both samples.
