dc.description.abstract	This work focuses on the study of mathematical aspects of upper critical magnetic field of superconducting HoM06SeS. At zero external magnetic field, HoM06SeS ) was found to undergo a transition from the normal state to the superconducting state at 5.6X and returned to a normal but magnetically ordered state between the temperature range of O.3K and O.53K. The main objective of this work is to show the temperature dependance of the upper critical magnetic field of superconduct ing HoMo Ses by using the Ginzburg-Landau(GL) phenomenological equation. We found the direct relationship between the GL coherence length(c;cd and penetration depth (ACL) with temperature. From the GL equations and the results obtained for the GL coherence length, the expression for upper critical magnetic field(H 6 tained for the superconducting HoM06SeS' The result is plotted as a function of temperature. The graph shows the linear de pendance of upper critical magnetic field(H is in agreement with experimental observations. c2 ) is ob c2 ) with temperature(T) and our finding Key ·words: Ginzburg-Landau equation, upper critical magnetic field and HoMo 6 Ses	en_US
