Semiconductor Skyrmion Velocity Vs Current Calculator
Extract actual signed tracked skyrmion velocities and current-density slope, no predicted universal Hall trajectory or drive-current advice.
Description
Tracked skyrmion displacement and elapsed time give signed velocity at each measured current density.
Tracked skyrmion displacement and elapsed time give signed velocity at each measured current density.1
Fitting those velocities summarizes a chosen branch’s current response.
When to use Semiconductor Skyrmion Velocity Vs Current Calculator
Use this tool when you need to reproduce the stated calculation from measured records or independently selected model inputs. Prepare measured device or specimen records under independently matched branch, temperature, frame, and unit conventions.
How to use Semiconductor Skyrmion Velocity Vs Current Calculator and understand its results
- Prepare measured device or specimen records under independently matched branch, temperature, frame, and unit conventions.
- Enter observedSkyrmionCurrentDensities, observedSkyrmionDisplacementsM, observedMatchedTrackingDurationsSeconds, following the field table and rules below, then run the tool.
- Read observedSkyrmionVelocitiesMSecond, fittedVelocityPerCurrentDensity, velocityFitRSquared. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedSkyrmionCurrentDensities | Observed skyrmion current densities | list of number | Required |
| observedSkyrmionDisplacementsM | Observed skyrmion displacements m | list of number | Required |
| observedMatchedTrackingDurationsSeconds | Observed matched tracking durations seconds | list of number | Required |
Use aligned current-density coordinates, signed displacements in metres, and positive tracking times in seconds. Require at least two distinct current-density values. Divide displacement by time, fit velocity against current density, and return velocities, slope, and R².
velocity_i=displacement_i/time_i; responseSlope=OLSslope(currentDensity,velocity) Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedSkyrmionVelocitiesMSecond | Observed skyrmion velocities m second | list of number |
| fittedVelocityPerCurrentDensity | Fitted velocity per current density | number |
| velocityFitRSquared | Velocity fit R² | number |

}Limitations and assumptions
Matched measurement branch, material state, calibration, and conventions must be independently established. Results do not certify device performance or operating conditions.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected. Evidence arrays must be dense, with no missing cells. Numeric observation lists allow at most 10,000 entries, subject to any smaller bounds stated above.
Alternative or Complementary methods
For a related review, use Semiconductor Skyrmion Size Calculator: A skyrmion size observation can be defined by where a radial magnetization trace reaches a declared boundary value. Multiple observed boundaries remain separate radii and diameters. For a complementary step, use Semiconductor Spintronic Magnetoresistance Vs Field Calculator: A field-resistance trace can be expressed relative to an actual zero-field resistance. Retaining signed changes distinguishes resistance increases from decreases.
