## Description

- description: The thermal diode is a growing technology and is important for active
    thermal flow control. Since the theoretical designing of thermal diode in 2004,
    various kinds of solid-state thermal diodes have been theoretically and experimentally
    investigated. Here, thermal rectification in bulk-size superconductor–normal metal
    junctions is reported. High-purity (5N) wires of Pb and Al are soldered, and the
    thermal conductivity (κ) of the junctions is measured in two different directions
    of the heat flow, forward (κF) and reverse (κR) directions. Thermal rectification
    ratio (κF / κR) of 1.75 is obtained at T ∼ 5.2 K with H = 400 Oe. The merit of
    the Pb–Al junction is a large difference of κ in the order of several hundred
    W m−1 K−1 and magneto-tunability of the working temperature.
