The three translational oscillations of this region are called the Slichter triplet. The anisotropy of this region was studied using PKIKP travel times. Discovered by Inge Lehmann, this region has a radius of about 1200 kilometers and a temperature comparable to the Sun's surface. This region is located below the layer that is responsible for Earth's magnetic field. This solid layer primarily consists of a nickel-iron alloy. For 10 points, name this layer that is surrounded by the outer core.
