This value was determined to decrease systematically a small amount with variation in the magnetic field and to be higher for the Y358sample. Similarly, without the magnetic field is 92.87 K for the Y358 sample and 82.83 K for the other sample although with the magnetic field of 5 T is 74.08 K for the Y358 sample and 32.44 K for the other sample. This value was decided to reduce systematically a big amount with variation in the magnetic field and to be larger for the Y358 sample. These results agree closely with studies in the literature.
