    Therefore, the Kerr images of the domain patterns can be considered as a viable direct mapping technique of an inhomogeneous current distribution. We then perform the same experiment using the t = 1.5 nm sample. Kerr images of the domains obtained with V = 9 V and τ = 10 ms are shown in Fig. 4F.

The following formula, from Roshenow and Griffith, gives the value of qmax in SI units, i.e., W/m2 [3]. Once the critical heat flux data is determined it is compared with the required heat flux data.

  • Ruby

    Ruby is a pink to blood-red coloured gem variety of the mineral Corundum. The name comes from the Latin word "ruber" - red. The red colour can vary within each individual deposit, therefore the determination of the source from the colour is not possible. The red colour is caused by chromium, and in case of brownish tones due to presence of iron.
