Abstract :
We analyzed the influence of temperature on the main characteristics of a passive spin-torque microwave detector (STMD): volt-watt sensitivity, signal-to-noise ratio, and minimum detectable microwave power. We reveal that these parameters do not always improve with the decrease of temperature. The developed formalism can be used for the optimization of the practical parameters of a STMD in a wide range of temperatures.
