Abstract: A magnetic storage device includes first and second magnetic layers and a non-magnetic layer, where the non-magnetic layer includes a first oxide layer containing magnesium and oxygen, a second oxide layer containing magnesium and oxygen, a third oxide layer containing zinc and oxygen, a fourth oxide layer containing a first predetermined element and oxygen, and a fifth oxide layer containing a second predetermined element and oxygen, and a crystal structure of an oxide of the first predetermined element and a crystal structure of an oxide of the second predetermined element are each a rock salt structure. The first predetermined element and the second predetermined element each have an oxide formation free energy greater than an oxide formation free energy of zinc, and the oxide of the first predetermined element and the oxide of the second predetermined element each have a bandgap narrower than a bandgap of an oxide of magnesium.

Abstract: An object of the present invention is to provide a beverage that not only allows for rapid replenishment of water, carbohydrate and salt for the purpose of taking measures against heatstroke but also is comfortably drinkable. It was found that sliminess, bitterness, bad aftertaste and unpleasant finish derived from sodium can be reduced by adding coconut water. It was also found that lauric acid, which is a fatty acid abundant in coconut water, exerts an effect to reduce sliminess, bitterness and other discomforts derived from sodium. The present invention provides a lauric acid-containing beverage which is comfortably drinkable since sliminess, bitterness and other discomforts derived from sodium present in the beverage are reduced.
